论文中提出一种高速数据传输系统的设计方案,用于提高数据采集卡中数据的传输性能。本方案基于PCI Express接口标准,利用现场可编程逻辑器件(FPGA),采用硬件描述语言Verilog HDL、模块化设计思想以及存储器直接访问(DMA)传输方式实现FPGA中的逻辑功能,最终实现数据的高速传输。经仿真与验证,本方案可行并能够满足高速数据采集卡中对数据传输部分的性能要求。

To improve data transmission performance of the data acquisition card, a design of High-speed Data Transmission System was proposed. Using Field Programmable Gate Array （ FPGA ）, adopting Verilog HDL of hardware description language, the design of modularization and DMA transmission way, it was implemented the logical function in FPGA, and eventually implemented the data transmission with high-speed. Through simulation and verification, this design was feasible and could satisfy the performance requirements of data transmission in the high-speed data acquisition card.
